ZF 4657.199.409 LOOSE PARTS for WG160/WG210 | OEM Genuine Part

Overview

The ZF 4657.199.409 LOOSE PARTS kit is a critical service component designed specifically for the WG160 and WG210 series transmissions. This OEM genuine assembly contains the necessary loose hardware and small components required to secure and align internal transmission sections during a rebuild or major repair. Positioned at the interface between the main housing and the front/rear sections, this kit ensures proper clamping force and alignment of the TRANSMISSION HOUSING and the HOUS.FRONT SECT. The SKU 4657.199.409 is a genuine ZF part, guaranteeing exact fitment and metallurgical standards for industrial drivetrain applications.

Symptoms of Failure

• Transmission oil leaks at housing joints: When the loose parts (bolts, pins, or plates) in this kit fatigue or loosen, oil can seep between the HOUSING REAR PART and the main case, leading to visible drips or wet spots on the bell housing.
• Gear slipping under load: Worn or missing fixing plates and pins can allow slight misalignment of the HOUSING REAR SECTION, causing gear engagement to become inconsistent, especially during high-torque shifts.
• Abnormal vibration or driveline noise: If the cap screws or cylindrical pins in the 4657.199.409 kit are compromised, the transmission housing can shift minutely, producing a low-frequency rumble or metallic chatter during operation.
• Difficulty in transmission reassembly: During a rebuild, if the original loose parts are reused, technicians often report that the housing sections do not mate flush, indicating that the hardware has stretched or deformed.
